Brain-computer interfaces are communication bridges between a human brain and external world, enabling humans to interact with their environment without muscle intervention. Their functionality, therefore, depends on both the BCI system and the cognitive capacities of the user. Motor-imagery BCIs rely on the users’ mental imagination of body movements. However, not all users have the ability to sufficiently modulate their brain activity for control of a MI-BCI; a problem known as BCI illiteracy or inefficiency. The underlying mechanism of this phenomenon (...) and the cause of such difference among users is yet not fully understood. In this study, we investigated the impact of several cognitive and psychological measures on MI-BCI performance. Fifty-five novice BCI-users participated in a left- versus right-hand motor imagery task. In addition to their BCI classification error rate and demographics, psychological measures including personality factors, affinity for technology, and motivation during the experiment, as well as cognitive measures including visuospatial memory and spatial ability and Vividness of Visual Imagery were collected. Factors that were found to have a significant impact on MI-BCI performance were Vividness of Visual Imagery, and the personality factors of orderliness and autonomy. These findings shed light on individual traits that lead to difficulty in BCI operation and hence can help with early prediction of inefficiency among users to optimize training for them. (shrink)

This book offers a significant reinterpretation of the history of republican political thought and of Niccolo Machiavelli's place within it. It locates Machiavelli's political thought within enduring debates about the proper size of republics. From the sixteenth century onward, as states grew larger, it was believed only monarchies could govern large territories effectively. Republicanism was a form of government relegated to urban city-states, anachronisms in the new age of the territorial state. For centuries, history and theory were in agreement: constructing (...) an extended republic was as futile as trying to square the circle; but then James Madison devised a compound representative republic that enabled popular government to take on renewed life in the modern era. This work argues that Machiavelli had his own Madisonian impulse and deserves to be recognized as the first modern political theorist to envision the possibility of a republic with a large population extending over a broad territory.

This study assessed challenges faced by researchers with the informed consent process (ICP). In‐depth interviews were used to explore challenges encountered by Investigators, Research assistants, Institutional Review Board members and other stakeholders. An electronic questionnaire was also distributed, consisting of Likert‐scale responses to questions on adherence to the ICP, which were derived from the Helsinki Declaration and an informed consent checklist of the US Department of Health and Human Research (HSS). Responses were weighted numerically and scores calculated for each participant. (...) The median score of the level of adherence to the informed consent process was 93%. Most of the respondents (60%) cited the lack of time for the ICP to be a challenge, with 65% indicating a lengthy consent document to be the main challenge with the informed consent document. Challenges with language and communication were the dominant theme among informants. Despite the high adherence of Ghanaian researchers and research assistants to the ICP, challenges are still prevalent, requiring diligent and continuous efforts in research implementation. (shrink)

The elimination of child marriage is a goal that ranks high on the agendas of civil society organizations, national governments, and multilateral institutions. To date, however, there has been very little scholarship on the historical debates over the definition of child marriage. This article examines the history of age-restricted marriage as it was debated during the development of human rights instruments in the post-World War II era. Using archives of the United Nations and affiliated organizations, we detail how and why (...) efforts to establish a universal minimum age for marriage were repeatedly unsuccessful. We illustrate how the current, commonly used definition of child marriage—as marriage before the age of 18—has never been agreed upon in a legally binding international convention but was seemingly established through a discursive innovation that borrowed principles from the 1989 Convention on the Rights of the Child.

Mindfulness-based training programs are highly established in competitive and recreational sports. One of the best-known approaches is the Mindfulness-Acceptance-Commitment Approach by Gardner and Moore), which integrates mindfulness aspects of awareness, non-judgmental attitude, and focus. Based on these aspects, Thienot and colleagues developed and validated an English language sport-specific questionnaire, the so-called Mindfulness Inventory for Sport, for the assessment of mindfulness skills in athletes. The aim of this study is to psychometrically test a German language version of the MIS. To assess (...) the psychometric properties, the MIS-D was examined in an online survey with an integrated test–retest design for reliability, validity, and measurement invariance. The present results support the psychometric quality of the German language version of the MIS. Necessary replications should among others focus on checking the measurement invariance for further relevant subgroups. (shrink)

_ Source: _Volume 30, Issue 2, pp 156 - 177 Using the example of ghosts and religion, this paper argues for the importance of social context and background operative in Hobbes’s account of social life and, in particular, the role of environment, education, and language in explaining much of what we think we know, and much of what we believe. The paper looks to aspects of Hobbes’s epistemology and his account of belief, to make the case that he recognizes how (...) a kind of social conditioning is required to sustain certain beliefs. The paper briefly concludes with a focus on the commonwealth itself and how the example of religion and religious belief extends to the commonwealth and the kinds of beliefs required for the commonwealth to sustain itself.

In contested areas of environmental research and policy, all stakeholders are likely to claim that their position is scientifically grounded but disagree about the relevant scientific conclusions or the weight of the evidence. In this article, I draw on a year of participant observation and over 110 in-depth interviews, with the case study of controversial chemicals used as flame retardants in consumer products. I develop the concept of strategic science translation, the process of interpreting and communicating scientific evidence to an (...) intended audience in order to advance certain goals and interests. Engaging in selective, interpretive, or inaccurate SST allows competing stakeholders to bolster their arguments, strengthen their authority, and inspire change regarding a policy-relevant issue. Because stakeholders deploy imbalanced resources when they participate in contested environmental fields, their actions in those fields and the resulting policy outcomes often reduce not to the settling of scientific truths but to power differentials.

Under the sign of Libitina, the Roman goddess of burials and funerals invoked in Horace's Ode 3.30, this essay provides a celebratory introduction to the work of the Polish Jewish poet Zuzanna Ginczanka, situating her within the cultural history of commemoration and consecration of the dead in Poland and the painful confrontation with the unburied dead of the Holocaust, of whom Ginczanka is one. Her best-known poem, a bitter parody of Juliusz Słowacki's “My Testament,” turns the Horatian notion of poetry (...) as the most precious and enduring legacy on its head by construing the author's meager household possessions, looted after her denunciation to the Nazis in wartime, as the only offering her fellow citizens will cherish, while the text itself was actually brought as evidence in a postwar trial of the Polish woman she accuses in the poem and contributed to a conviction for collaboration. Using historian Thomas Laqueur's terms necro-sociability and necronominalism as competing impulses in a seemingly intractable struggle, this essay argues that it is possible to find in Ginczanka's joyful defiance of traditional accounts of body and spirit the point of departure for a poetics that claims a new freedom of imagination in the attempt to transcend the most stubborn of memory wars.

In the fast-paced world of clinical medicine, recognizing and acknowledging differences in worldviews is often overlooked. When dealing with the delicate issues broached in advance care planning, such oversights can lead to deep rifts within the health care provider-patient relationship. By providing guidance to those engaged in such endeavors and setting advance care planning in a global context, health care practitioners will be better able to care for their patients and achieve the noble goal of advance care planning_giving volume to (...) the voice of the patient in the last chapter of her life.

Born at 24 weeks gestation, Baby G now lies in a neonatal intensive care unit two months post-birth. He has pulmonary hypoplasia, congenital scoliosis, and swallowing issues that will require placement of a feeding tube, and bowel dystonia that interferes with his ability to absorb feedings. Shortly after birth, he experienced a cardiopulmonary arrest and now has obvious neurological impairments. As a result of incomplete development of his lungs and severe chronic lung disease, he cannot breathe on his own. Because (...) of his chronic respiratory failure, tracheostomy and long-term assisted ventilation was offered as an option that would allow him to be discharged from the acute care setting. However, his congenital.. (shrink)

To liberate African philosophy from the remnants of the colonial style of thought, Kwesi Wiredu promotes the idea of the conceptual decolonization of African philosophy. He argues that, to accomplish this project, African philosophers must theorize in African vernaculars. This article attempts to show that the project of the conceptual decolonization of African philosophy by recourse to theorizing in African vernaculars is challenging. It examines a particular strategy that Wiredu deploys in “Conceptual Decolonization as an Imperative in Contemporary African Philosophy,” (...) in which he hopes to demonstrate that the Akan conception of mind is superior to the Cartesian conception of mind. It demonstrates that Wiredu’s attempt to show the superiority of the Akan conception of mind is unsuccessful and that his project of conceptual decolonization fails. Nevertheless, it concludes that Wiredu’s conceptual decolonization project still shows promise even in light of our criticisms. (shrink)

The "best interest of the child" standard is central to both pediatric bioethics and the child rights community. In pediatric bioethics in the United States, the best interest of the child standard is cited as the guidance principle for parental decision-making.1 Likewise, in the child rights community, the best interest of the child standard is "of paramount consideration" ). Both approaches also recognize parental rights and responsibilities and support a role for the maturing child in the decision-making process. Why, then, (...) do members of the pediatric bioethics community and the child rights communities not speak the same language?This article was developed out of... (shrink)

The act of drawing a line or uttering a word is often seen as integral to the process of making art. This is especially obvious in music and the visual arts, but applies to literature, performance, and other arts as well. These collected essays, written by scholars from diverse fields, take a historical view of the richness of creation out of nothing (creatio ex nihilo) in order to draw out debates, sometimes implicit and sometimes formally stated, about the production and (...) reproduction of cultural meaning in a period of great change and novelty, between the beginnings of the medieval intellectual tradition and the imprint of the Enlightenment. The authors pose the following questions: Do tradition and creativity conflict with one another, or are they complementary? What are the tensions between composition and live performance? What is the role of the audience in perceiving the object of art? Are such objects fixed or flexible? What about the status of the event? Is the event part of creation, in the sense that it disturbs the still waters of historical continuity? These and other questions build on the foundation of Roland Barthes' concept of Degree Zero, offering new insights into what it means to create"--Back cover. (shrink)

It is undeniable that people have beliefs about what actions are morally right. These beliefs play an important role in guiding moral action. Is it possible however to justify beliefs about what actions are morally right? How can beliefs of this sort be justified? Sinnott-Armstrong has advanced an epistemic regress argument against the justification of moral beliefs with the consequence that moral beliefs cannot be justified. This essay addresses the issue of the justification of moral beliefs to answer the question (...) about how moral beliefs can be justified in response to Sinnott-Armstrong’s epistemic regress argument. It argues for the plausibility of Rawls’ reflective equilibrium as an adequate method of justification of moral beliefs. Three problems arise in the attempt to show that reflective equilibrium can adequately respond to Sinnott-Armstrong’s regress argument. These are vicious circularity, arbitrariness and epistemic moral disagreement. It is shown in this essay that these problems can be satisfactorily dealt with. (shrink)
